Calcium Containing Patents (Class 424/602)
  • Patent number: 6485751
    Abstract: This specification discloses resorbable calcium phosphate-based bio-compound particles and the manufacturing method thereof. Through the manufacturing process control, collagen has sufficient time to reconstruct and forms a network structure, which then combines with calcium phosphate-based ceramic powders that are controlled to have diameters ≦5 &mgr;m so as to provide a bio-compound acceptable by humans and having a similar structure and constituents to the bony tissues. There is no need for a second operation when such material is used in medical practice and the bony tissues can undergo fast and effective bone-genesis.

  • Publication number: 20020155167
    Abstract: The present invention provides a novel process for producing a calcium phosphate cement or filler which hardens in a temperature dependent fashion in association with an endothermic reaction. In the reaction a limited amount of water is mixed with dry calcium phosphate precursors to produce a hydrated precursor paste. Hardening of the paste occurs rapidly at body temperature an is accompanied by the conversion of one or more of the reactants to poorly crystalline apatitic calcium phosphate. The hardened cements, fillers, growth matrices, orthopedic and delivery devices of the invention are rapidly resorbable and stimulate hard tissue growth and healing.

  • Patent number: 6462022
    Abstract: The present invention relates to a pharmaceutical composition comprising lisinopril and dibasic calcium phosphate dihydrate (DCPD), produced by a process comprising mixing lisinopril and DCPD with a specific surface area of less than 1.5 m2g−1. The use of large particle sized DCPD in a lisinopril formulation/composition has the effect of reducing the amount of the lisinopril degradation product DKP that is formed, thereby increasing the shelf-life of tablets formulated with the larger sized DCPD, particularly those with low doses of lisinopril.

    Abstract: What is shown is an animal blood anticoagulant compound useful in the meat packing industry generally, and in slaughterhouse operations, particularly. The anticoagulant is effective when diluted with water at higher dilution ratios than earlier anticoagulants. In some field trials, this anticoagulant was at least as effective as previously known commercial anticoagulants when diluted by an additional 30%. The present anticoagulant preparation concentrate is an aqueous mixture of soft water (55.0%-65.0/%, w/w); tetrasodium ethylene diamine tetraacetate (Na4EDTA) (0.5%-3.0%, w/w); sodium hexametaphosphate (17.0%-24.0%, w/w); citric acid (5.0%-9.0%, w/w); and sodium hydroxide (4.0%-7.0%, w/w) to obtain a balanced pH that provides optimal chelating and anticoagulant activity. Optimal anticoagulant performance has been found to occur in the range of between pH 6.6 and pH 7.2.

  • Patent number: 6383519
    Abstract: Shaped, preferably porous, inorganic bodies are provided which are prepared from a reactive blend. In accordance with one preferred embodiment, the solution is absorbed into a porous sacrificial substrate such as a cellulose sponge. The solution-saturated substrate is heated and an oxidation-reduction reaction occurs thereby forming an inorganic solid. A shaped, inorganic body is formed in situ. Optional, but preferred additional thermal treatment of the shaped, inorganic body removes the organic substrate, leaving an inorganic body that faithfully mimics the porosity, shape, and other physical characteristics of the organic substrate. Inorganic substrates may also be used to good effect. Large varieties of shaped bodies can be prepared in accordance with other embodiments of the invention and such shapes find wide use in surgery, laboratory and industrial processes and otherwise. The invention also provides chemically and morphologically uniform powders, including those having uniformly small sizes.

  • Publication number: 20020034646
    Abstract: Biomaterial, for example bioactive silicon, may be fabricated by anodizing a silicon wafer to produce a wafer having a porous silicon region. In vitro experiments have shown that certain types of porous silicon cause the deposition of apatite deposits both on the porous silicon and neighboring areas of bulk silicon when immersed in a simulated body fluid solution. This deposition of apatite provides an indication that porous silicon of appropriate form is bioactive, and therefore also biocompatible. A form of porous silicon is dissolved in the simulated body fluid solution and this is an indication of a resorbable biomaterial characteristic. In addition to porous silicon, certain types of polycrystalline silicon exhibit bioactive characteristics. Bioactive silicon may be used in the fabrication of biosensors for in vitro or in vivo applications. The bioactivity of the bioactive silicon may be controlled by the application of an electrical potential thereto.

  • Patent number: 6214368
    Abstract: The present invention provides a novel process for converting a standard inert amorphous calcium phosphate precipitate into highly reactive amorphous solids. The amorphous solids can be used to react with other calcium phosphate solids to form a poorly-crystalline synthetic hydroxyapatite that provides both bioactivity and structural integrity. This novel amorphous material can be reacted with other calcium phosphates at or below 37° C. to form a bone-like material consisting of poorly crystalline hydroxyapatite.

  • Patent number: 6129928
    Abstract: This invention encompasses porous, nanocrystalline, biomimetic calcium phosphate coatings of the order of 2-30 microns that can be grown on metal implants. The chemical surface treatments and methods for making the calcium phosphate coatings are disclosed. Post treatment with dilute hydrogels such as phema reinforce the inorganic structure and enhance the mechanical strength of the coatings. Methods are also disclosed for adsorbing or covalently attaching growth factor proteins to derivatives of the hydrogel coated calcium phosphate coatings. Such hydrogel reinforced calcium phosphate coatings show equivalent bone tissue growth as the currently used implants and are easily resorbed. This property in combination with the immobilized growth factors is expected to enhance the process of osseointegration of the disclosed coatings.
